AUGUSTUS WALTON, OF SAN FRANCISCO, CALIFORNIA.

CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 287,202, dated October 23, 1883.

Application filed May 14, 188 3. (No model.)

To aZZ whom it may concern:

Be it known that I, AUGUSTUS WALTON, residing at San Francisco, in the county of San Francisco and State of California, have invented a certain new and useful Improvement in Car-Axles, of which the following is a specification. I

My invention relates to adivided car-axle having a central coupling, as hereinafter more fully described and claimed.

A A represent the axle, which is divided in the middle and bored from end to end, in order that a channel, A, may be provided, through which a lubricant may be caused to flow for the purpose of lubricating the parts inclosed by the coupling-sleeve.

The inner ends of the divided axle are hollowed out in a cup-shaped form, anda recess, A", is thus provided, which forms a reservoir for theoil .or other lubricant, and from which it may work its way along between the opposed faces of the divided axle, and thence along the surface of the axle next to the coupling-sleeve, and up to and about the retainingcollars, a sufficient space being left between the parts to avoid friction. The outer ends of these oilchannels are closed by screwplugs A A Near the inner end of each section of the divided axle I make an annular groove. with i this groove is placed a collar, B, the outer f e of which projects some distance beyond th face of the axle and forms a flange or ared shoulder, as shown. This collar or fl ge may be made of cast-iron and in two or more sections, and held in place by screwin C, as shown; or it may be made of one iece of metal and shrunk on; or it may be cast entire with the axle.

D is a short sleeve adapted to be placed over and around the meeting ends of the divided axle, and has a circular rabbet, B, or enlargement of the bore, formed in each head, for the purpose of receiving-the projecting shoulders of the collars or flanges B B, and in practice the coupling-sleeve is first passed over the inner end of one axle, and the end of the other axle is then inserted into the sleeve, the collars B fitting into the rabbets B, and being flush with the outer faces or heads of the sleeve. 50 While in this position the caps E E are screwed down upon the heads of the sleeve D by means of screw bolts F, the heads of which enter dovetailed countersunk cavities or cups G G,

formed in the faces of the caps, and are packed 5 5 number of parts, which parts are all of simple construction, with little, if any, liability of becoming broken asunder or disconnected, and that the parts can be operated with but a small amount of friction.

It will also be seen that old axles can be cheaply altered over and my improvementapplied to them, and that in rounding curves in the track each wheel will regulate itself and the coupling or sleeve will revolve with the axle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A divided car-axle composed of the tubular sections A A, the ends of which are closed by screw-plugs A A, the hollow couplingsleeve D, having rabbeted ends, the collars B B, caps E E, and screw-bolts F F, substantially as shown and described.

2. In a divided car-axle, the sections A A, having a central bore or oil passage, A, their outer or supply ends being closed by screw-plugs A A and their inner ends hollowed out to form a cavity or oil-chamber, A in combination with a coupling-sleeve, substantially as shown, and for the purpose speci fied.

In testimony that I claim the foregoing I have hereunto set my hand and seal.

AUGUSTUS WALTON. [L s.]
